Dataset consists of DataTable collection which consists of 
DataRows. Create Dataset object, then create DataRow object

Dim objRow as New DataRow

objRow(9) to objTow(19) woud give the rows between 10 and 
20, as first row is stored with index 0.

We can use DataTable.Select method to fetch rows. see the 
following example:
In this 
customerTable.Select( strExpr, strSort, 
DataViewRowState.Added ) fetches the records which is 
greater then 5.

Private Sub GetRowsByFilter()
    
    Dim customerTable As DataTable
    customerTable = new DataTable( "Customers" )

    ' Add columns
    customerTable.Columns.Add( "id", GetType(Integer) )
    customerTable.Columns.Add( "name", GetType(String) )

    ' Set PrimaryKey
    customerTable.Columns("id").Unique = true
    customerTable.PrimaryKey = new DataColumn() { 
customerTable.Columns("id") }

    ' add ten rows
    Dim id As Integer
    For id = 1 To 10
        customerTable.Rows.Add( _
            new object() { id, string.Format("customer{0}", 
id) } )
    Next id
    customerTable.AcceptChanges()

    ' add another ten rows
    For id = 11 To 20
        customerTable.Rows.Add( _
            new object() { id, string.Format("customer{0}", 
id) } )
    Next id

    Dim strExpr As String
    Dim strSort As String
    
    strExpr = "id > 5"
    ' Sort descending by CompanyName column.
    strSort = "name DESC"
    ' Use the Select method to find all rows matching the 
filter.
    Dim foundRows As DataRow() = _
        customerTable.Select( strExpr, strSort, 
DataViewRowState.Added )
    
    PrintRows( foundRows, "filtered rows")

    foundRows = customerTable.Select()
    PrintRows( foundRows, "all rows")
End Sub

Private Sub PrintRows( rows() As DataRow, label As String)
    Console.WriteLine( "\n{0}", label )
    If rows.Length <= 0 Then
        Console.WriteLine( "no rows found" )
        Exit Sub
    End If
    Dim r As DataRow
    Dim c As DataColumn
    For Each r In rows
        For Each c In r.Table.Columns
            Console.Write( "\t {0}", r(c) )
        Next c
        Console.WriteLine()
    Next r
End Sub

objRow(9) to objTow(19)

mentioned above would return the column index and would not 
return the loop.

Corrrect me if I am wrong

for(int 
RowsCount=1;RowsCount<dataset.rows.count;RowsCount++)
{
    if(RowsCount>10 && RowsCount<20)
     {
       //if you GirdView or DataGrid 
        Gridview1.DataSource=dataset;
        GridView1.DataBind()

     }
}

DataRow[] dr = new DataRow[10];
for(int i = 10 to 19)
   dr[i] = DataSet1.Tables[<TableIndex>].Rows[i];

DataRow array dr contains Records between 10 and 20.

DataSet ds = new DataSet();
        ds.Load(cmd.ExecuteReader(),
LoadOption.OverwriteChanges, "sample");

        DataRow[] dr = ds.Tables[0].Select("id>1 and id<10");

        for (int i = 0; i < dr.Length; i++)
        {
            Response.Write(dr[i][0].ToString()+"<br>");
             
            
        }

We have the option of the fetching the starting record and
the maximum record options.

_dataadapter.Fill(_dset,"Test",11,10);

It will retrieve the record from 11 to next 10 records.

_adapter.Fill(ds,11,10).
or By iterate record from 11 to 20.
